The budget solution for an indoor grow area is a so called 'quantum board'. This is an LED panel where white higher end LEDs are directly mounted to a board inside a alu casing. The aluminum hood acts as the passive cooler. Then the power supply/driver is mounted on top of that. The most famous example is Viparspectra P1000.
These are generally 100 to 150 watts, 150 to 200 USdollar products that can be used to grow a single cannabis plants quite well.
Given that cannabis plants require a lot of light, these products are also very good for growing other plants indoors.
Spending more money for a dimmable product could be a good idea.
Check out this video:
Guy tests a whole bunch of grow lights, low to high end, using a high end sensor designed to measure photosynthetically available radiation (PAR).
You want to consider the cost of the lamp itself, the amount of plant growth it can provide (PAR), and the electricity(plus cost) it requires to do so.
So you want something with both a high efficiency (above 1.8 joules/mole) and a low product price. How much light you need depends on how large a grow area you have.
I think he also tested some of the HLG products that cmeg1 suggests. cmeg1' suggestion seems like an excellent example of a current good quantum board. But not suitable for shelving. Of course, shelving can save you indoor space.
Only some products fit with shelves. Most products you have to hang from a growth tent or the ceiling. You will have about 1.15 square meter of grow area. If you want to provide a PPFD of 350 umoles/second/m2, then you need a total PAR of about 400 umoles/second. With a very efficient light of 1.8 joules/mole, that will be 225 watts. Just some numbers to think about.
Maybe you can find one that is shaped linear? Then you have to think carefully at what height you need to mount them to get a good coverage.
